For their anterior three-fourths the corpora cavernosa penis lie in intimate apposition with one another, but behind they diverge in the form of two tapering processes, known as the crura, which are firmly connected to the rami of the pubic arch.
Traced from behind forward, each crus begins by a blunt-pointed process in front of the tuberosity of the ischium.
Just before it meets its fellow it presents a slight enlargement, named by Kobelt the bulb of the corpus cavernosum penis.
Beyond this point the crus undergoes a constriction and merges into the corpus cavernosum proper, which retains a uniform diameter to its anterior end.
